.CYLINDER PRINTING-MACHINE.

SPECIFICATION forming part of LettersPatent No. 687,030, dated November 19, 1901. Application filed November 13, 1899. Serial No. 736,892. (No model.)

To all whom it may concern:

Be it known that we, JAMES HUNTER, residing at 6 Clydesdale road, Byker, Newcastleupon-Tyne, county of Northumberland, and WILLIAM HUNTER, residing at 23 Inkerman street, Stockton-on-Tees, county of Durham, England, subjects of the Queen of Great Britain, have invented certain new and useful Improvements in Cylinder Printing-Machines, of which the following is a specification.

Our invention relates to improvements more particularly in what are commonly termed cylinder printing-presses.

It has for its object, among other things, to provide especially for imparting the requisite rotary and longitudinal or endwise reciproeating motion to the ink-distributing roll or rider to enable it to properly apply the ink to the inking-rollers, above whichitis mounted, to provide for the ready adaptation or application of the ink-distributing roll or rider to machines wherein the inking-rolls are not geared; also, to otherwise promote convenieuce, facility, and compactness of the arrangement of the parts.

It consists of the combination, with an inkdistributing roll or rider whose shaft is suitably geared to a rack carried by the reciprocating bed of the machine, of a forked or bifurcated traveling nut or carrier adapted to suitably embrace or engage said shaft and itself engaged or actuated by a worm or threaded extension of a shaft properly journaled and carrying a pinion engaging or gearing with said rack, said traveling nut or carrier being suitably guided by a pin or slide supported and bearing in the frame of the ma chine, all substantially as hereinafter more fully disclosed, and specifically pointed out by the claim.

The accompanying drawing is a longitudinal sectional view illustrating the preferred embodiment of our invention.

In carrying out our invention we employ in connection with the ordinary reciprocating bed A carrying the usual rack B, the inking-rolls A and the ink-distributing roll or rider A, arranged above the latter rolls. The rolls A and A, respectively, have one end of their shafts A A, respectively, journaled in the standards or uprights G G, respectively,

"mounted .upon the machine-frame F, preferably as shown.

thereof to permit of endwise or longitudinal movement or reciprocation, as presently more fully described.

The reference letter C denotes a broad toothed pinion mounted on the shaft A gearing with the reciprocating rack B for the rotation of said roll or rider to aid in properly applying or distributing the ink upon the inking-rolls A.

The reference-letter F denotes a bracket mounted upon the machine-frame F and provided with inner and outer bearing-standards (l G respectively. In the former is journaled the other end of the shaft A of the roller A, and in the latter is journaled the other end of the shaft A of the roller or rider A. A worm or screw-threaded shaft E is suitably journaled in the bearing-standard G of the bracket F, preferably as shown, and is geared with and driven by the rack B by means of a pinion B, secured to one end of said worm-shaft E. The pinion B, carried by the worm-shaft E, also meshes with the pinion (J, carried by the shaft A Mount-ed on the worm-shaft E is a nut or carrier D, which is engaged by said shaft E and moved longitudinally thereof. Said nut or carrier Dis provided with a forked or bi- The shaft A of the roll or. rider A extends outwardly from each end furcated elongation adapted to embrace or engage a peripherally-grooved disk or collar D, fast to the shaft A of the ink-distributing roll or riderA. This arrangement, it will be seen, provides for transmitting an endwise or longitudinal reciprocating movement to the inking-roll or rider A to further aid in the proper distribution or application of the ink to the inking-rolls A, the rotary action of said roll or rider A applyingthe ink to the latter rolls, the two motions of said ink-distributing roll. or rider A thus serving to effect the thorough and uniform distribution of the ink upon said inking-rolls. The tread or face of the pinion O is of course constructed in such a manner as to provide for its engagement with the pinion B, while allowing for the endwise movement of the rider or ink-distributing roll A. In orderto effect the retention in proper position of the traveling nut or carrier B, it

is provided with a pin or slide H, projecting or extendinghorizontaily therefrom and hearing or riding in an opening in the outer bearing of the bracket F, carried by the frame F. From the foregoing the operation and ad vantages of our invention are clearly apparent and therefore need not be further emphasized or elaborated herein.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

The combination in a printing-press, of the machine-frame thereof, a pair of standards mounted thereon, a bracket mounted on said machine-frame and provided With an inner and outer bearing-standard, an ink-distributing roller having its shaft journaied at one end in one of said standards and at its opposite end in the outer bearing-standard of the bracket, inking-rollers journaied in the other of said standards and in the inner bearing of the bracket, a Worm or screw shaft journaled in the outer bearing-standard of the bracket, a reciprocating table mounted on the machine-frame and provided on its upper face with a rack, a toothed pinion mounted on the inner end of said worm-shaft and geared with the said rack, a broad-faced toothed pinion mounted upon the shaft of the ink-distributing roller and adapted to gear with the pinion carried by the Worm-shaft, a collared disk fixed on the shaft of the ink-distributing roller, a nut or threaded block mounted on, engaged and operated by the said worm-shaft and provided with a bifurcated projecting arm engaging with and operating said disk for imparting a reciprocating movement to said ink-distributingroller, and a guide pin or bar connected to said block and extending through the outer bearing-standard of the said block, substantially as herein described and for the purpose specified.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
